The activation method is proposed for collection of the sufficient statistics during the investigation of the nuclear astrophysical reactions at low energies with the short-living residual nuclei formation. The main feature is a multiple cyclical irradiation of a target by an ion beam and measurement of the radioactivity decay curve. The method was tested by the yield measurement of the 12 C( p ,γ) 13 N reaction with detecting the annihilation γγ- coincidences from 13 N(β + ν) 13 C decay at the two-arm scintillation spectrometer.

Angular distributions of differential cross sections have been measured for elastic, inelastic scattering and the ( He 3 , d ) reaction on 6Li nuclei at the E lab ( He 3 ) = 34 MeV energy. The new and early obtained elastic scattering data at 34, 50, 60 and 72 MeV have been analyzed with Coupled Reaction Channels Method (CRC) taking into account triton transfer mechanism. The spectroscopic factors for t + He 3 configuration of 6Li were extracted. Parameters for real part of potential have been also calculated microscopically with double folding model. The differential cross sections for proton stripping to the 7Be ground and first excited states have been analyzed by modified DWBA and CRC methods at 34 MeV. The effect of triton and α exchange on proton transfer reaction Li 6 ( He 3 , d ) Be 7 for both ground and excited state is discussed. Spectroscopic factors and asymptotical normalization coefficients for p + Li 6 configuration of 7Be have been obtained from the experimental data.
